I said throttle body kit, like an Omex / Jenvey kit, or a Weber Alpha kit

Kits come complete with all the management, and some hotter cams. Standard fuel pump is used.

I budgeted £500 for a complete mapping session. £2k kit... £500 mapping... £300 manifold... £200 is not enough for other little bits and pieces, but that's how I arrived at £3k
